IMPALA-2302: Use a permitted value for parquet.block.size while loading nested tpch.
IMPALA-2302: Use a permitted value for parquet.block.size while loading nested tpch.

Due to a possible change in behaviour in Hive/MR, it is no longer possible to use
arbitrarily large values for parquet.block.size. This breaks the loading of nested tpch
data on newer Hive. This patch addresses the problem by using a permissble value.
